The St. Gallen Company sells home corona saliva tests; You have to know it
A company in St. Gallen sells a new crown test that you can order at home and that does not require smears. 4 questions and answers.
How does the saliva corona test work?
It is a saliva test that you can order at home. The test does not require a smear, the test subjects can take their saliva themselves and then analyze it in the laboratory. Therefore, a nasopharyngeal smear is not necessary, which is uncomfortable for most people.
The person doing the test can spit their saliva into a tube with a funnel at home, at the doctor, or at the test center. Once the sample is taken, it is sent to the laboratory. You should receive the result by email on the day of receipt.
Is this crown test a safe alternative?
The manufacturer, Home Sampling GmbH, writes in a press release that according to a Yale University study, the detection sensitivity of Sars-CoV-2-RNA in saliva is comparable to or better than that of a nasopharyngeal swab.
Didier Trono, head of the “Diagnosis and Testing” expert group at the Federal Crown Task Force, contradicts this. “New studies show that saliva tests are a little less sensitive,” he tells Watson. However, the difference is not too great. So most infections can be found with saliva tests. Infectious people in particular can be safely encountered with it. A saliva test is also a more suitable variant, especially for children.
Ultimately, though, it’s a matter of ability, according to Throne. Like conventional nasopharyngeal swabs, saliva tests are analyzed using the PCR method. “So if supplies are running low because the frequency of testing is increasing in view of the high number of cases and the excessive positivity rate in Switzerland, then nasopharyngeal swabs for PCR analysis should be prioritized.”
“In an ideal world, saliva antigen tests would be available that could detect all contagious people,” Trono said. But the combined reduced sensitivity of antigen testing and saliva as a sample source does not yet allow this.

Why have you never heard of this crown test?
We can only speculate as to why saliva testing was hardly discussed in Switzerland. The St. Gallen manufacturing company writes in its announcement that the tests are already being used in the US and Canada. In the United States alone, the University of Kansas tested 30,000 students in this way.
Didier Trono of the task force, on the other hand, says the studio situation has simply been too thin so far. “There have been studies, but most of them were not well controlled and were based on too limited a number of samples.” Therefore, the scientists disagreed on the efficacy of the tests.
How much does this saliva corona test cost?
The saliva test is available online for CHF 157. If you do not want to pay the costs yourself, you need a doctor, a test center or an approved pharmacy.
However, it is stated on the manufacturer’s website that claims receipts are not generated for the health insurance company.
